[PATCH v3 1/8] drm/dp: Add defines for DP SDP types

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add defines for the secondary data packet (SDP) types from the spec.
These are the DP specific ones, and in addition HDMI infoframe types
(see enum hdmi_infoframe_type) are also valid SDP types.

v2: Add more SDP types
v3: Note the DP version that added each SDP type (Rodrigo)
